Abstract
The present disclosure provides systems and methods for utilizing two or more magnetometers for current measurements. The systems and methods may include two or more multi-axis magnetometer sensors to monitor a high-voltage three-phase alternating current (AC) transmission line carrying a current, I. The magnetometers may be positioned at varying distances from the transmission line. The systems and methods may isolate or otherwise account for external magnetic fields, such as the earth's magnetic field, to generate accurate current measurements in a conductor.
